The Tönnies Group has built its bovine animal competence center in Badbergen, Lower Saxony. The cuts of beef are vacuum-packed in thermoforming and shrink-wrap machines, a course of that has turn out to be more environment friendly than ever following renovations on the web site: Now, energy-saving Atlas Copco variable-speed vacuum pumps are used to create vacuum situations at two central stations.What used to be a blended slaughterhouse has become a “bovine animal competence center”: For many years, cattle and pigs have been slaughtered and butchered on the similar time in Badbergen on behalf of other corporations. In 2017, the Tönnies Group took over the positioning and determined to base its entire slaughtering operation in Badbergen – up till that point, this had taken place on the company’s main web site in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the site after in depth conversion and renovation. The Group invested round eighty five million euro within the building and state-of-the-art technology at this website in a small town in northern Lower Saxony, between Oldenburg and Osnabrück. The slaughtering, butchering and finishing processes are based on the latest cooling know-how, machine-based butchering and highly automated picking and transport strains.
Several hundred tons of meat go away the location daily and 95% of the animal – practically every thing – is utilized. This allows Tönnies to fulfill completely different eating habits all over the world: While German customers favor lean beef, meat with a thick layer of fats is in style in Scandinavia and other European nations, based on the manufacturer’s web site.
Efficient screw vacuum pumps provide forming, low and fine vacuums
“The cuts weigh between 1.5 and 9 kilograms after butchering,” explains Waldemar Metzger, Technical Manager of Tönnies Beef GmbH & Co. KG in Badbergen. The cuts are vacuum-packed for various major prospects. For this objective, Tönnies has put in several packaging traces within the halls: Seven thermoforming curler machines and two robot-operated shrink-wrap packaging machines. Efficient Atlas Copco vacuum pumps are used in the methods to hoover pack the tubular/shrink luggage and thermoformed plastic trays, and to maintain the meat really contemporary. They work in two stations and supply forming, low and fine vacuums.
The thermoforming machines equipped by vacuum station 1. There are 4 Atlas Copco GHS 585 VSD+ variable-speed, oil-injected screw vacuum pumps that evacuate the air up to 40 mbar (absolute), in addition to four small boosters that lower the stress even additional to 3 mbar. One of the screw pumps provides the forming vacuum for the thermoforming roller machines, which only require round a hundred to a hundred and fifty mbar for the forming course of. The different vacuum pumps on this station are related to the boosters. One of the pumps is redundant at any given time: This can be the case within the second vacuum station, which includes five GHS 730 VSD+ pumps that take away the air from the shrink bags at the Cryovac lines. “The size of the cuts of meat is routinely detected by our techniques,” explains Waldemar Metzger. “The packaging machines then routinely insert the cuts of meat into the tubular luggage, that are minimize to the correct measurement under a vacuum bell.” Under the hood, all ambient air is then evacuated in two stages till the pressure is round 3 mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s additionally called – the plastic tray is fashioned by chopping the foil roll,” says the Technical Manager. After filling the shell with smaller pieces of meat, the shell is “wed” to the quilt film: The device closes and seals the packaging airtight at three to five mbar using the fine vacuum. Sorting machines assign the individual trays and tubular luggage to bigger boxes, that are then used to select custom boxes for customer orders.
Efficient velocity regulation reduces power necessities by a third or extra
Waldemar Metzger has been working in Badbergen for 20 years and has been a half of the planning and execution levels of changing the mixed slaughterhouse to a purely beef operation from the very beginning. This included the choice to purchase Atlas Copco variable-speed vacuum pumps. “As far as expertise is concerned, being ready to vary the pace of the GHS vacuum pumps is essential to us and saves energy,” stresses the Tönnies employee. “Compared to fixed-speed machines, you can reliably cut down vitality necessities by around a third – perhaps even by half, relying on the range factor.”
The controls on the vacuum pumps have a user-friendly plain textual content display, which additionally indicates the operating hours and upkeep intervals. Since the Atlas Copco pumps can be linked directly to an exhaust system, it was attainable to use air-cooled pumps. According to the manufacturer, this improves the local weather of the room; it’s now not necessary to have the extra room cooling often required when using central vacuum systems.
The challenge was carried out on web site by and with Oliver Hornberg, Managing Director of Eugen Theis Vakuumtechnik in Werther. He delivered the pumps to Tönnies Beef, prepared to make use of – including a four hundred m pipeline in the transformed slaughterhouse, measuring in places to a diameter of DN 300. His firm, Eugen Theis GmbH, was based in 1984 and makes a speciality of vacuum expertise. In 1999, Hornberg took over the enterprise from its founder, Eugen Theis, and 20 years later, in late 2021, offered it to Atlas Copco after he could not find a successor. “Our two youngsters are pursuing other profession paths,” he says. Hornberg himself stays Managing Director even after the company was offered to Atlas Copco and is looking forward to vital development underneath the umbrella of one of the world’s largest suppliers of vacuum pumps. เครื่องมือที่ใช้วัดความดันคือ operates all through Germany: “From Flensburg within the north to Regensburg within the south and Halle (Saale) within the east,” he says, outlining the reach of his firm: This also consists of Badbergen in the (north)west, as he sometimes stops by at Tönnies Beef to maintain the machines.
